TOOL FOR REMOVING VALVE SPRINGS.

Application filed July as,

To aZZw/wmitmay concern: I a Be it known that we, EARLlV; Sonnniinn- HORN and Roswnnn l i oonnnrr, citizens of the United States of America, residing at Schenectady, in the county of Schenectady and State of New York, have invented cer tain new and useful Improvements in Tools for Removing Valve Springs, oi which the following is a specification.

@111 invention appertains to'tools for re moving valve springs "from automobile engines particularly those of the overhead type, and the object of our invention is to provide asimple and effective tool by the aid of which pressure may he applied to the valve spring cap and the spring compressed so as to expose the pin, or forked washen used to trap the spring in a position where it may be easily gripped by a pair of pliers or other suitable tools and be removed from the valve stem.

Our improved tool isillustrated in the accompanying drawings in which:

Fin-5. 1 is a side elevation id illustrates our tool being used to expose a i rhed washer on the end of a valve-stem. 1

i Fig. 2 is a front elevation and illustrates our tool being used to expose a pin through the end of a valve stem.

The s no reference characters refer to the same pa ts tiroughout the several views.

' mg to the draivin is the shank or? our tool and is preferably made from uitahle dimensions. one end of the t and ada'i'ited to he inlr'. 'llhe other end is f C and drawn so as to form a. comp-urn sharp annular ridge 1) about the openi n l The piece is then bent to shape :nbstantially as illustrated.

in many ot the automobile'e ines which use overhead type valves, the spring is capped by termed washer shaped substantially as the washer 2' illustrated in the drawings and having a depression ll in the top thereof adapted to receive the forked washer L (or the pin. N) and to prevent its accidental removal.

in order to remove the Forked washer (or pin) it is necessary to compress thevalve spring S, so that the end of the valve stem, with the forked washer, (or pin) will be l lo pierced by an o 1321. S eria1 No; 487,591.

above the spring cap so that the washer (or pin) may be withdrawn and the valve released.

Our tool is adapted to facilitate the removal of such washers or pins. The opening C is of suliicient diameter to permit the free passage therethrough of the end of the valve stem and such pin or washer, and by placing the tool in position over the end of the valve stem and against the spring cap and exerting pressure on the handle the spring and spring cap may be compressed until the spring cap 'is below the end of the valve stem and the washer .or pin. adapted to contact with the depressed portion H of the washer on spring cap G as illustrated and to keep the tool concentric with the valve 'stem and also to prevent the tool from slipping.

We claim I v 1. In a tool for use in removing valve springs from automobile engines, a springcap engaging member with an opening therethrough adapted to pass the end of the valve stemand the means used to prevent the removal or said'spring cap from said valve stem; a shank portion extending from one side or said spring-capengagin g portion and extending upward and inward to a point substantially in line with the center of said opening shank. 1

2. In a tool for use in removing valve springs from automobileengines a springcap engaging member with an opening therethrough adapted to pass the end of the valve and a handle on the end of said The annular ridge ,1) is stem and the means used to prevent the re EARL W. sonnnni nnonn; ROSWELL woonnnrr.
